    Hi all. I am Jasper I am an ebike bike designer, I grew up in UK now living in Singapore

    Wrong starting point IMO there, that's a "stylist" job, a bike "designer" should put function way over "looks", the stylist just tidying it up finally. ;) Sadly, though that's not the way of the world these days, from buyer reflecting right back to the producer. Sorry Woosh, just a very raw...

    Hub gears v derailleur

    With my Nexus 8 there is only a need to take the torque I apply off as I change gear, no need to stop pedaling or back pedal. The crank drive itself also automatically is powered off for a moment as the gears change, it has a sensor to signal this in the gear change cable.

    Riese and Müller Homage GT Vario - second impressions

    Thank you for an interesting read, both re the bike and the routes taken. On the point of using cycleways on disused railway tracks, is the "Cinder Track" itself a rewarding ride, in that close by I have the "Meon Valley Track" but this is grossly spoilt by the growth of the track side...

    Suspension seat post advice please

    There is also the depth of the saddle itself, not all are the same and unfortunately gaining saddle compliance type comfort goes hand in hand IME with greater saddle depth.

    Thinking now is it all worth while ?

    Much a side issue, but one these photos share with many from the past, even our family album, is the "ears". What has generically happened, exceptions accepted, that today they are far more streamline? Could it be the advent of the bike, the greater speed of travel, so the chilling effect has in...

    Thinking now is it all worth while ?

    Then of course cross bar frames have, to my knowledge, not been the exclusive domain of males. My wife through our decades of cycling used cross bar frames, some even specifically designed and sold for the female skeleton's geometry.

    Thinking now is it all worth while ?

    But, would the likes of a Claude Butler really have benefited at all from gaining a suspension fork or to any great extent from disc brakes? The lovely swept chrome moly steel forks worked well and sapped little energy, and out of any mud plugging role the rim brakes coped, if not perfectly...

    First e-Bike (Somewhat overawed and confused...!) - Help / Guidance appreciated

    This thread also addressed some of the issues between the two bikes, technically IMO you have by far the better of the two. Better engineered hub gear, bigger battery, and much better belt drive...

    Thinking now is it all worth while ?

    Whilst a big advocate on test riding a few e-bikes before buying, I can't see it adds anything at all to knowing how reliable any will be? Test riding reveals how the bike, the drive and the drive's electronic management feels, and here there can IMO be big differences. I found cadence based...

    First e-Bike (Somewhat overawed and confused...!) - Help / Guidance appreciated

    When it comes to leaving it parked up somewhere, looking rather understated, might have its attractions? What really have you to gain from others being very attracted to your bike, your really the only one who needs to know how great a bit of kit it actually is, well IMO.

    Review Whats the diffrence btween both e-bikes ?

    Dérailleurs have their place, foremost they are cheap, also they are light, serviceable, offer a wider gear range and can be quite efficient, so in that are a natural choice for both the budget and the more sporting enthusiast user, particularly where the use is in more severe terrain. [Though...

    Review Whats the diffrence btween both e-bikes ?

    That in itself is IMO a very big plus together with being technically kinder to the hub gear, which is also a better quality hub gear. Then there is that higher energy storage battery. So, apart from the aesthetics in your eye's, I feel it looks more like all pluses going for the Centros.

    Review Whats the diffrence btween both e-bikes ?

    One was a £2850 bike, the other is a £2150 bike, but to me it is the 8 speed Nexus gear, is IMO a far better engineered gear than the cheaper Nexus 7 speed. Nothing to do with an extra gear, but its better engineering technology. The more rugged technology of the Nexus 8 being a benefit in the...

    Impulse 2 Charger

    What picture, the one that was flagged up? Charger That one illustrated is not even for the Impulse 2, the thread subject. I have seen no other picture of the correctly configured charger, indicating only two wires are used. The web page very clearly states to message them about the charger...

    Impulse 2 Charger

    Clearly, as I responded some time before you "updated" your post reading it would, shall we say, have been quite obviously "challenging". Whilst I could tear into the cable, the charger or the battery I shall not be doing so. The charger itself, I have checked and they accredit the following...

    Impulse 2 Charger

    Similarly, it is naive just to assume they don't serve some functions, even if not functions replicated in cheaper options? A case where to know what if anything they do is a far better informed position than assuming.

    Impulse 2 Charger

    Even if the plug case does not contribute yet an additional connection, there are already 4 pins involved, hinting there could be more to replacing this charger than DIY cobbling up an alternative charger to apply a potential to the battery?

    Hub motor v Mid drive motor?

    Bikes like many things are riddled with potential single point failure, features, it does not reflect a flawed design, it reflects more a considered design approach involving a huge chunk of "probability of failure". A puncture, a failed road wheel axle or rim, a headstock or even the frame...

    Impulse 2 Charger

    From what I read on "Pedelecs" of owners experiences with the Impulse 2, are there not many "spare" chargers out there?

    first time ridding for real

    Is that just an issue with cadence only sensing or a full power throttle, as I only have user as opposed to demonstrator experience of torque sensing, and simply can't understand that "warning" in the context of modern controls? Back on subject, I would take a universal tool to reset things...
